Date: Sun, 27 Dec 2015 18:19:23 -0500 From: Michael Chan <mchan@...adcom.com> To: <davem@...emloft.net> CC: <netdev@...r.kernel.org> Subject: [PATCH net-next 06/12] bnxt_en: Don't treat single segment rx frames as GRO frames. If hardware completes single segment rx frames, don't bother setting up all the GRO related fields. Pass the SKB up as a normal frame.
